The Research on Electrical Source about High Electric Potential of Active Optical Current Transducers;

Study the Active Reactive Power Compensation;

The corn sacchrification liquid by double-enzyme hydrolysis could be a main carbon source for L-lactic aid fermentation,then suitable organic nitrogen sources for lactic acid bacteria TL-2 was explored.

The production of erythromycin in the shake flask is apparently influenced by adding different kinds of organic nitrogen source.

Bsaed on the traditional process of producing Jinggangmeisu with residue, a new one residue free is developed via selecting the strain and replacing organic nitrogen source partially with inorganic nitrogen source.

Distinguished from public,communal and contigeous resources,mutual resources is the open zone of the combination of enterprise and market,and also the virgin land of theoretical understanding.

Hydrocarbon expulsion characteristics of effective source rock in Talimu Craton Basin and their significance of petroleum geology;

Most of active headsets, which use fixed analog feedback controllers, are not able to maximize the noise reduction.

In this paper, the characteristics, development and the state of the art of the active headset are discussed, and then the structure, algorithm and engineering implementation for analogue and digital active headset are investigated respectively.
